An Oliver Ames student-athlete has been charged after he struck and killed a 71-year-old Easton man Monday morning while walking his dog on Summer Street.

Charges were filed against Colin O'Hearne, 17, of Olivia Road, Easton, on Tuesday for negligent driving resulting in a death, speeding and failure to to stay in marked lanes, according to Police Chief Allen Krajcik.

The victim was George E. Power, 71, of North Easton. Power was taken by ambulance to Good Samaritan Hospital, where he was pronounced dead.

O'Hearne is a student at Oliver Ames High School and plays for the football team. Coach Jim Artz said O'Hearne attended a 6 a.m. practice Monday, which concluded between 8:30 and 9 a.m.

Artz declined to comment further, but it appears O'Hearne was on his way from the high school when the crash took place.

Police said O'Hearne was traveling east on Summer Street when he lost control of his car, striking Power before crashing into a tree and then a utility pole.

As of Monday evening, charges have not been filed against O’Hearne. Police said charges against O’Hearne will be sought in Taunton District Court pending the outcome of their investigation. The investigation is being conducted by Easton Police with assistance from state troopers.

Easton Fire Capt. James Walsh said the call came in at 9:22 a.m. Witnesses reported that a man was hit on or near the side of the road in front of 24 Summer St. and slammed into a tree. When rescue workers arrived, he was on the ground next to the tree, his shoes 50 feet from his body.

Neighbors said they heard the accident and rushed outside to see a black Infiniti sedan pressed into a utility pole. A tree on the other side of the street was damaged where the vehicle originally struck.

It appears the car hit the tree and spun out, hitting a utility pole on the other side of the road. The dog also died in the crash.

One of the neighbors, John Monroe, said he did not realize at first that a pedestrian was hit. O'Hearne was walking around outside the vehicle and appeared shaken, he said.

Monroe said his son called police to report the accident, and they called back again once they realized someone had been struck. Police were on the scene within moments of the second call, he said.

Monroe did not know Power, but said he often saw him walking his dog in the area.

Power was the husband of Chris Power, chairman of the physical education department at Oliver Ames and cheerleading coach. Reached at their North Easton home, Power’s family declioned to comment.
